I've always envied the JVM's class reloading abilities. Edit-n-continue in Visual Studio has so many "it doesn't work if you do this" cases, that's it next to useless.
I would love to be able to put the C# debugger into interpreter mode and be able to change anything, anywhere while debugging and keep on trucking without having to stop debugger, make changes, restart debugger, etc..
